.DJUSTABLE NOZZL'E FOR ATOMZXNG.- OEIL.

Application filed January 9, 1915.

i To all whom it may concern:

` Be it knovvr that l, RUSSELL A. Munn, a citizen of the United States, residing at Detroit, in the county of Wayne, State of Michigan, have'invcnted certain new and useful improvements in Adjustable Nozzles for Atomizing Uil; and l do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to Which it appere tains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, Which `form a part of this specification.

This invention relates to oil atomizing nozzles especially adapted for use in connection With forced feed lubricators, and consists in the novel construction and arrangement of parts as hereinafter set forth and claimed.

The object of the invention is the provision of simple and eiiicient means -for regulating and controlling the delivery of oil injected by a Jforced feed lubricator into'the steam intake pipes of engines, pumps and other steam units requiring lubrication, s0 as to spray or atomize the oil at its point of discharge into the steam, to render it more volatile'and cause it to readily diffuse and vaporize, and become suspended and `entrained in the moving column of steam,

to be conveyed and distributed thereby upon -the Walls and rictional surfaces of the engine cylinders in a film of lubricant.

The invention contemplates such a construction of the device by which the above object is attained, as Will provide for adjustment to accommodate it to varying sizes of steam pipes and enable the delivery end of the device to be positioned substantially centrally of the diametric area of the pipe so as to discharge the oil axially of the column of steam and cause it to diuse raidially and distribute uniformly therein.

Provision is also made for checking the oil against back flow by the steam pressure and for adjustably controlling the discharge openings to regulate the relative proportions of the oil and steam to be saturated and accommodate the varying requirements of the lubrication desired. v

The preferred embodiment of the novel features of construction comprising the Specification of Letters atent.

present invention is illustrated in the accompanying drawings7 in which:

Figure l' is detached perspective ofthe device constructed in accordance With my invention, showing the partsV assembled in position for operation. Fig. 2 is a vertical longitudinal sectional vievv through the device showing it attached to and extending longitudinally through the Wall and into a vertical section of steam pipe, a portion of the wall of which is broken away to show the parts in position therein.

Referring to'the drawings by the characters of reference marked thereon, l designates the device which in general may be termed a nozzle, and 2 indicates a steam 'pipe'through the wall of a vertical section of which the nozzle is adapted to extend in a horizontal plane 'with its inner end terminating centrally of the interior of the pipe. The nozzle is constructed in two parts and consists of a body portion comprising a nut having a laterally extending exteriorly screw threaded sleeve l adapted to tit tightly into a screw threaded aperture 5 'formed through the Wall of a steam pipe 2, as shown in Fig. 2. Extending centrally through the nut 3 is a screw-threaded bore 6 which receives the threaded end of an oil supply pipe 7 adapted for attachment With a source of oil supply, preferably from a forced feed sion for the sleeve 4, and carrying thereon a' jam nut 1l for engagement `with the end of the sleeve to detachably loclr said stem therein and permit of its longitudinal adjustment to vary the length of the nozzle by screwing it into or out oit' said sleeve. j

The inner or reduced end 9 of the stem is provided with a central longitudinal bore forming a passage l2 which communicates With the bore 8 of the sleeve It, and also With a mixing chamberl formed by counterboring into the outer end of the stem 10. An annular shoulder 14 is thus formed at the juncture of the chamber 13 and passage l2, in which a ball 15 may be seated to serve as a check valve to prevent the back flow of oil or steam through said passage. The outer end of the chamber 13 is interiorly 'to the plug 16 as to enable one or more of said slots to be closed or restricted through the turning of said plug to move it axially of the mixing chamber, whereby the volume of discharge through said orifices may be regulated. Steam is admitted to the mixing' chamber through an elongated aperture or port 19 extending through the wall of the 'stem 10 opposite to and inclined toward the discharge orifices and communicating with said chamber midway its length in vertical diagonal relation to said orifices.

The parts being thus constructed and assembled, and the nozzle attached to a steam pipe in the position shown in Fig. 2, the operation of the device will be as follows: The `oil being fed under pressure from a lubricator (not shown) will fiow from the supply pipe 7 through the sleeve 6 into the passage 12, and with each impulse of the lubricator the ball 15 will be unseated against the tension of its spring, and a quantity of oil -will be injected into the mixing chamber 13. A portion of the live steam passing vertically through the pipe 2 will enter the mixing chamber through the port 19,' and in passing therethrough and out of `the orifices 18 will be caused to travel in a diagonal course, encountering and entraining the oil in the mixing chamber and ejecting it therewith in jets of spray through the discharge orifices into the body of moving steam. The high temperature of the steam acting upon the atomized oil will cause it to diffuse in a vapor, saturating the steam in which it will be conveyed and distributed in a film deposit of lubricant upon the-walls and surfaces of the engine cylinders, or other surfaces requiring lubrication to which the steam is admitted.

It will be apparent from the foregoing that an oil atomizing nozzle embodying the present construction is adapted to a wide range of use, that owing to its adjustabili'ty it may be readily altered in length to adapt it to steam pipes of various diameters and so position the'discharge orifices as to deliver the oil centrally within the column of steam and insure its uniform distribution, and that through the adjustment for controlling the discharge orifices, the delivery cil be gaged and accurately proportioned with the volume of steam to minimize waste and meet v the actual requirements of the work to be lubricated.

Having thus fully set forth my invention, what l claim as new, and desire to secure by Letters Patent, is:

1. An oil atomizing nozzle comprising a hollow sleeve .having means for attachment to a steam pipe and adapted for connection with a source of oil supply,` a stem extensible in said sleeve, a chamber in said stem and an oil passage communicating with said chamber and said sleeve, a steam inlet port communicating with said chamber through the wall of said stem upon one side, an oil discharge orifice communicating with one end of said chamber through the opposite wall of said stem, and a check valve in said chamber for closing the oil passage thereto.

2. An oil atomizing nozzle comprising a hollow sleeve screw-threaded for attachment to a steam pipe and for connection with an oil supply pipe, a screw-threaded stem adjustable in 'said sleeve, a mixing chamber in said stem and an oil passage communicating with said chamber and with said sleeve, a steam inlet port communicating with said chamber upon one side thereof, a plurality of oil discharge orifices communicating with said chamber upon the opposite side thereof, and a plug for closing the end of said chamber and adjustable therein for restricting said orifices.

3. An oil atomizing nozzle comprising a hollow sleeve screw-threaded for attachment to a steam pipe and for connection with an oil supply pipe, a screw threaded stem adjustably secured in said sleeve, a mixing chamber in said stem and an oil passage communicating with said chamber and with said sleeve` a check valve in said chamber normally closing said passage, a steam inlet port communicating with said chamber upon one side thereof, a. plurality of oil discharge orifices communicating with said chamber upon the opposite side thereof, and a plug adjustable in said stem for restricting said orifices and for closing the end of said chamber. l
